Monitoring policy creation foundation

Upgrde to xacml v2.0.0 release artifact.

Some re-arrangement of classes. New class to support a
common dictionary among the monitoring applications. I
may move it to a common under the main since some of the
values are shareable.

Created application service provider, so the XACML
main knows what policy types are pre-loaded and can
report them back to the PAP.

struggled with cucumber, which does not create
TemporaryFolder although the documentation says its
supported.

Added a new Policy Finder specific to ONAP which does
quicker job to load policies.

Issue-ID: POLICY-1273
Change-Id: I4af15a64da3b42d48f29809710421b1649625adc
